Clock Frequency Division Switching Confirmation
3.14.3.4.1
Function Details
Using the API, the frequency division ratio of the target clock can be changed. You can confirm the currently
selected frequency division ratio from the register.
Clock Frequency Division for the System and I/O Processor, AHB, and APB
The clock (ck_cpu_bus_gear_1) for the System and I/O Processor, the AHB clock (ck_ahb_gear), and the APB
clock (ck_apb_gear) are frequency divided clocks of the ck_cpu_bus. The frequency division of the ck_cpu_bus is
described by the following equations.
